Call based-dos .exe file, but how to input the parameters and get the text on DOS screen?

Yes, I have searched the similar topic before posting this topic. 

I understand we can use standard input for parameters input of system exec.vi, but still can't find any answer about "how to get the text on DOS screen".

1. Attached sw500912_2701test.exe is the based-dos exe file, (change .tar to rar)

2. Double click .exe, run this file. The first parameter is band rate, default is 9600.

3. Setting the COM #

to get the output text set wait till completion to truew (default i think) then wire the standard output. It returns a multiline string of the output

Hope it helps

Thanks for your reply. I thought so as well before, but it seems failed to receive the data from standard output.

May be worth checking the command is actually running. when the dos window pops up is there any text?

try cmd /c "<insert command>"

Thanks, i understand a little. Because didn't complete the DOS .exe file implement, maybe the text data can't pass to the front panel.

Cant you add the parameters of the com-port to the command call? Similar to "TarToRar -c 1 -b 9600 -f file.tar -o file.rar"?

Yes, I can. I find the reason that why no output. 

Because it fail to jump out of loop of DOS .exe, can't output the text of screen. Thanks for your reply.
